CVE-2026-63045 is a server-side request forgery vulnerability in Apache HTTP Server's mod_proxy_ftp module affecting versions 2.4.0 through 2.4.68 on all platforms. Improper validation of the address supplied in an FTP passive-mode (PASV) reply allows an untrusted upstream FTP server to cause an Apache forward proxy to open a data connection to an arbitrary third-party host. Apache HTTP Server 2.4.69 fixes the validation flaw.
